VGB Statement: Analysis of the impact of reactive power supply on electrical components

For the delivery of ancillary services, voltage stability and reactive power, to the transmission network, among others generating plants / power plants are used.

For the determination of all reactive power-related expenses the respective investment share, stronger wear and the resulting maintenance as well operation expenses have to be considered.

In the VGB statement an overview on the evaluation of plant-specific shares of investment, maintenance and operation will be given. This includes results of the research projects “Investigation of wear mechanism caused by reactive power load change of generators” (Sensoplan) and “Wear of electrical components caused by reactive power supply” (Hochschule Ruhr-West).

The VGB Statement is available in German only.

VGB-S-219-00-2015-03-EN - Refractory Lining in Fluidised Bed Combustion Plant - Now available as eBook!

Refractory lining is an essential design element of steam generating plants with fluidised bed combustor. Economy and availability of fluidised bed combustion depends to a large degree on the quality and availability regarding service life and load following capacity of the refractory lining. Hence, it is obvious that this lining is, hence, to be manufactured, installed and operated with great care.

The VGB-Standard VGB-S-219-00-2015-03-EN offers suggestions for manufacturers and operators regarding design, ordering, procurement, materials supply, installation, drying, operation and maintenance. It intends to facilitate making clear agreements on the refractories and on requested services between the contract partners.
